Abstract
The utility model discloses a device for preventing a through-flow type air opening of a blast furnace from moving outside, which belongs to the technical field of blast furnace air opening equipment, and is used for preventing an accident caused by move-out of the through-flow type air opening in the blast furnace air opening equipment. According to the technical scheme, the device comprises a supporting seat, an ejector rod, an ejector rod seat and a pin shaft, wherein the supporting seat is fixed on the outer wall of the blast furnace below a large sleeve of the air opening; the ejector rod penetrates through chambers of the large sleeve and a middle sleeve of the air opening; the front end of the ejector rod pushes against the rear part of the through-flow type air opening, and the rear end of the ejector rod is connected with the ejector rod seat in a welding manner; and the ejector rod seat is positioned on the supporting seat, and is fixedly connected with the supporting seat through the pin shaft. The ejector rod of the device pushes against the rear end of the through-flow type air opening, so that the through-flow type air opening is prevented from moving outside, a terrible accident caused by move-out of the through-flow type air opening is avoided, and smooth production can be guaranteed. According to the device, the large problems influencing production are solved, the cost of cast iron is reduced, and the labor intensity of operators is reduced. The device is simple in structure, convenient to use, easy to manufacture, good in effect and great in economic benefit.
Description
Technical field
The utility model relates to the throughflow tuyere in a kind of iron work blast-furnace tuyere equipment, belongs to the blast-furnace tuyere equipment technical field.
Background technology
Air port equipment is the key equipment in the blast furnace iron-making process in the Iron and Steel Production, high-temperature hot-air is sent into by blast-furnace tuyere, air port equipment is by being followed successively by cover, throughflow tuyere assembly in tuyere big sleeve, the air port in outer the reaching, wherein the throughflow tuyere assembly is made up of throughflow tuyere, water inlet pipe, return water pipe, in the cavity that belly pipe is combined to form by air port equipment hot blast is blown in the stove.Because hot blast temperature is up to 1200 ℃, outwards do not blow out for making hot blast, must guarantee to overlap in throughflow tuyere and the air port and contact the position and closely cooperate.But in the actual use often since throughflow tuyere be subjected to the blast furnace inwall come off slag crust impact and move outward, the gap appears in the cover matching part in throughflow tuyere and the air port, this moment, high-temperature hot-air blew out from the gap, warm sludge ejection in the stove causes the throughflow tuyere scaling loss when serious, and water-cooled tube distortion fracture loses cooling effect, and then can cause the serious accident of air port equipment burnout even blast, this moment, damping down stopped production immediately, changed throughflow tuyere assembling and belly pipe, had directly influenced production.
The utility model content
Technical problem to be solved in the utility model provides a kind of device that prevents that the blast furnace throughflow tuyere from moving outward, this device can be avoided irritating accidents such as slag because throughflow tuyere moves the air port scaling loss, the blowpipe that cause outward, thereby avoid damping down to stop production and change equipment such as throughflow tuyere and belly pipe, guarantee carrying out smoothly of production.
The technical scheme that solves the problems of the technologies described above is:
A kind of device that prevents that the blast furnace throughflow tuyere from moving outward, comprise bearing, push rod, tip-lever support, bearing pin in its formation, bearing is fixed on the high furnace outer wall of tuyere big sleeve below, push rod passes in tuyere big sleeve, the air port and overlaps chamber, the front end of push rod withstands on the rear portion of throughflow tuyere, rear end and the tip-lever support of push rod are welded to connect, and tip-lever support is positioned on the bearing, and tip-lever support is fixedlyed connected by bearing pin with bearing.
The above-mentioned device that prevents that the blast furnace throughflow tuyere from moving outward, connective slot is arranged at described bearing top, the axis normal of connective slot is in high furnace outer wall, the bottom of tip-lever support is embedded in the connective slot, there is bearing pin the top of bearing connective slot, bearing pin is positioned on the axis of connective slot, and axis hole is arranged on the tip-lever support, and the shaft hole sleeve of tip-lever support is connected with bearing on bearing pin.
The above-mentioned device that prevents that the blast furnace throughflow tuyere from moving outward, there is baffle plate the rear end of described bearing, has wedge that tip-lever support is fastening between the rear end of baffle plate and tip-lever support.
The beneficial effects of the utility model are:
The utility model is not done change to blast-furnace tuyere equipment primary structure, has increased push rod and bearing, and push rod withstands on the rear end of throughflow tuyere, prevents that throughflow tuyere from moving outward, has avoided taking place because throughflow tuyere moves the accident that causes outward, has guaranteed carrying out smoothly of production.The utility model has solved the big problem that influence is produced with less input, has reduced pig iron cost, has avoided the generation of pernicious industrial accident and security incident, has alleviated working strength of workers simultaneously.The utility model is simple in structure, easy to use, making is easy, respond well, and favorable economic benefit is arranged.
